TOPPING A50S Balanced Headphone Amplifier AMP Preamplifier

 Meet The New A50sTOPPING designed the aluminum chassis of the new A50s for maximum durability and heat dissipation. The casing CNC-machined to precision from a solid block of aluminum and accommodates a thermal conductive column. The thermal column transfers the heat generated from the op-amps and power supply to the surrounding aluminum case dissipating the heat.Optimized design allows the A50s to maintain its tiny footprint preserving a good appearance with no seams or visible screws. Aluminum is an excellent material because of its high thermal conductivity and structural strength. Ultra-High Performance Balanced NF ModulesNF modules result from TOPPING's intensive research and development into headphone amplification technology and the flagship A90 was the first amplifier from TOPPING that incorporated these modules. NF modules ensure low noise levels and distortion under all conditions and when used with all headphones.The A50s leverages TOPPING's revolutionary NF (Nested Feed Co
